Haweswater Reservoir

The main visitor access is at Mardale Head, at the southern end of the reservoir. An information board marks the circular route around the water, which takes about five to six hours for a full circuit. You can get a good feel for the landscape from a shorter lakeside outing, but this is not a flat, fully surfaced promenade. The far side can be uneven and rough, and some versions of the circuit use road walking, so sturdy footwear matters.

Haweswater is managed as a drinking-water reservoir and is also an important wildlife landscape. Look up toward the crags for peregrines, and scan the becks and wooded edges for dippers and redstarts. The water supports schelly, a protected whitefish, along with other lake fish, though seeing one is not a realistic visitor expectation.

The reservoir was created by damming the original lakes in the Mardale valley. The old village of Mardale Green was vacated before the water rose, and its drowned valley is part of the place's story. The result feels less like a conventional recreational lake and more like a high mountain valley shaped by a water-supply project.
